hi
my mh light are bleaching my coralline.....what can i do to.....
I don't get any coraline growth under my 250w MH either, on the undersides of the rock and the sides of the tank I get a lot of coraline growing. I don't think it grows well under such bright lighting.
Do you want to replace MH or T5 bulbs?
mh...mine are high because there the double ended..and there 250w
